DIN EN 15316-4-2:2017-09

This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement. The standard provides a calculation method under steady conditions that corresponds to one calculation step. The results of this calculation are incorporated in larger building models and take in account the influence of the external conditions and building control that influence the energy requirements for heating supplied by the heat pump system. In Germany, the Directive on the energy performance of buildings (2010/31/EU) of the European Parliament and the European Council is primarily implemented by national energy conservation law. National energy conservation law refers to dated national and European standards and national prestandards that have been specified to be implemented in Germany. On the basis of the dated references, only the editions of these technical rules addressed in this manner are used. If the dated technical rules to be used under energy conservation legislation refer to undated technical rules, the latter shall be used in the version that corresponds to the status at the time of publication of the dated technical rule. This document has been prepared by Technical Committee CEN/TC 228 "Heating systems and water based cooling systems in buildings" (secretariat: DIN, Germany). Working Committee NA 041-05-01 AA "Energetic assessment of building services installations (SpA ISO/TC 205 "Environmentally friendly building design")" at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS) of the German Institute for Standardization e. V. is responsible for the German version.
